Be it known that I, AooLrH J. Pn'rrsn, a citizen of the United States, residing at Los Angeles, in the county "of Los Angeles and State of California, have invented certain new and useful Improvements in Vehicle Frames, of which the following is'a specifi- The hereinafter described invention 1 lates to an improved ..jo'inted frame con- -struct ion or running gear, adapted for use in connection with all types of vehicles, but

is more particularly-adapted for niotor Ve-f" hicles, and has for its principal object to provide avehiclebody supporting frame so constructed that all road shocks Willbe absorbed or equalized'thereby before the same.

{are transmitted to the vehicle body, so that the vehicle occupantswill not be'jarredand jolted as the'vehicle wheels encounter rough:

or uneven surfaces;- L I A further object is to providefiaiframe of .the above mentioned type which will absorb" each road shock as it is independently trans- 'mitted thereto by the various vehicle supporting wheels; 4 a

"Other and important objects are to provide a device of theabove mentioned type in which the flexibility of th'shock absorbing medium may be varied according to the load carried by the vehicleor the road over which the vehicle is-to travel, and one in which the 4 frame.

shocks received by the supporting wheels will beiequally distributed throughout the The invention consists of a pair of alined side member s extending parallel :to each other and providin avehiclefrainefeach side member forme of a plurality of sec-' tions pivoted together at their-ends, the outer ends of the end sections-carrying the vehicle supporting wheels, brackets support- -'ing the vehicle body above the frame and connected thereto at-the pivotal'points thereof, and resilient means associated with the pivotalpoints of-thesectionsifor compensating and absorbin "the road shocks trans- A mitted from the ve icle Wheels before the same are transmitted to the vehicle body.

With the above mentioned and other objects in view, the invention consists in the.

' Yconstruction and novel combination of parts hereinafter fully described, illustrated in .the

. 'accom' anyl ng sheets of drawings, and

ointe out in theclaims hereto appended; being understood that various changes in vnnictn-rnamn Specification of Letters Patent. I j Pate t d r 3, Application filled June 27 1912. Serial 110,706,203.

The sections 5 entend longitudinally of a-vehicle body G'adjacent the sides thereof j and support thesame bymeans of a plurality of brackets 7, theupper ends of which are attached to the undcrsideof the ve hicle body and the lower-ends of .the brack ets', resting on transversely extending mag; which provides a point about which the meeting endpprtions ,ofithe side sections 5 pivot-, Themeetlng ends of the side sect ons 5, are

seated suitable bearings plates 13 shutting d 8 and plates being retained b rains sections by w h tit onto-the ends of the rod and irom the above constructioii it will be observed that an anti-friction bearing provided-at the: niceti ends of the side sections and thetensioii of the same may be varied by the adjustment of the "huts l5.

Extending laterally. from the side sec tions at their meeting ends are suitable in.- cl ned arms 16 between the ends of which is adapted to be positioned an inflatable or other form ofresilient member or bnfifcr 1? the resiliency of which will equalize and absorb the road shocks as they ere tensmi ted thereto through the side frame sections 5. The buiiers are connected. together by a suitable tube 17, and common inflation valve 3.7 isprovided, so that both buffers may be inflated to the some pressure and when one is compressed the air therein will escape to the other buffer.

The castings 2 are connected by a transversely extending rod 18, which serves to maintain the wheels in. alineinent and suitable coiled and leaf springslg'and 20 are provided intermediate the endsof the veill hicle body 6 .a nd the castings 2.

In Fig. 5

these shocks are absorbed by apair of in iiatable buiicrs 25 retainedwithin a casing 26 between thcend walls thereof, and projections 27 on the lower ends of the arms 24. These buffers are connected together by a suitable tube 28 sothat upon one being .of the arms and aj'pair'of concave bufier springs engage the outer faces ofthe ends of the arms, th'eiension of the respective compressed the air "therein will be forced is disclosed a" form of spring pairs of springs being regulated by the op i positely screw threaded members 29 and 30 which extend'int'o suitable screw threaded.

openings in the; springs;

From the above constructions it will observed that a vehicle frame has been provided which will .receive and absorb the shocks before the same are transmitted to the vehicle body, It will also'be observed that the equalizing buffers may be used separately or several be combined in a vehicle,

it only requiring that the meeting ends of the side sections be the some.

Having thus fully described my invention what isclailmed as new and desired to be protected by Letters Patent is- 1 1.111 a shock absorbing and equalizing frame for vehicles and in combination with. the vehicle body and supporting -wheels lOi thereof, a plurality of alined side sections arrangedin pivotal relation atv their meeting ends and tormlng a body supporting frame, brackets carried by the vehicle body, a shaft extending through said brackets and about, which said slde sections pivot, disks positioned over said shaft and engaging the opposite side faces of the side section for retaining the r meeting ends 1n PIVOtiLl "engagement, devices pivotally mounted on the free ends of said side sections for attachinentto said vehicle supporting whcels and buffers associated with the side sectionsof said supporting frame adjacent the pivotal I points for equalizing and absorbing the road shocks received from the veh cle "supporting" wheels before the same we transmitted to .m
